TELEGRAPH-POLE AND THE LIKE.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Application filed May 22, 1909. Serial No. 497,728.

To all whom it may concern:

Be it known that I, BRODERICK HAsKnLL, a citizen of the United States,residing at Franklin, in the county of Venango and State ofPennsylvania, have invented ccr tain new and useful Improvements inTelegraph-Poles and the Like, of which the following is a specification.

My invention relates to the construction of metallic poles for telegraphand like use, and particularly to a type of such poles wherein a seriesof preferably three legs or uprights are secured in proper convergingrelation to each other by transverse bands bolted or otherwise securedthereto at proper intervals.

The matters of invention consist in improved means and devices forrigidly and effectively securing said bands to the uprights in a mannerto effect great strength combined with ease of manipulation andsembling.

The invention will be clearly understood from the following detaildescription taken in connection with the accompanying drawings and thenovel features will be thereafter particularly pointed out in theappended claims.

Referring to said drawings; Figure 1 is a transverse section through anassembled pole adjacent one of the securing bands. Fig. 2 is afragmentary elevation of a portion of a pole showing a band in place onthe uprights. Fig. 3 is a detail vertical section on line TIL-III ofFig. 1, showing details of the securing devices. Fig. 4 is a like detailvertical section taken at right angles to that of Fig. 3 and showing amodified form, and Fig. 5 is a detail perspective of a novel form offilling block forming a part of the construction of Figs. 1 to 3.

The uprights 1 are preferably formed into U shape from plate materialand the bands 2, are of substantially triangular form, suitably recessedat the corners thereof to closely embrace the said uprights as shown at4. The straight parts of the bands between such recesses are in the bestembodiment of the invention, and as shown at 3, dished or corrugated toattain greater strength and rigidity in said members. Filling blocks 5are provided, the same being shaped to fit the interior of the uprights,except that the sides thereof are tapered or drawn inward at anintermediate point as shown at 6 for a purpose that will presentlyappear. As shown in Figs. 1 to 3 and 5 said blocks are provided at thefronts thereof and adjacent such drawn in portions with spaced apartlugs 7, forming between them a bolt receiving recess 8.

In assembling the pole, the bands 2 are placed upon the uprights 1, thefilling blocks are arranged within the uprights as shown and bolts 5)inserted through holes formed therefor, in the bands 2, the intermediateportions of said bolts lying as shown in the recesses 8. Upon theapplication of suitable nuts 10 to said bolts and the tighteningthereof, it will be seen that the underlying portions of the bands 2 anduprights 1 will be compressed and warped inward into the shallow recessformed by the drawn-in portion (3 of the filling blocks, thus rigidlyand reliably securing the parts together. If desired in this form, as inthat shown in Fig. 4, the bolts 9 may be also let into recesses 8 in theuprights l to further insure the same against displacement.

The form shown in Fig. 4 is further modified in that a recess to receiveabout one third of the diameter of the bolt is formed in the blocks 5instead of the employment of lugs 7 as in the preceding form.

Having now fully described my invention, what I claim as new and desireto secure by Letters Patent is as follows:

1. A structure comprising two hollowed out members, one partly wrappedaround the other, means for warping the same to gether, and means forrigidly clamping said members after a determinate amount of suchwarping.

2. A pole comprising U shaped legs, transverse bands secured thereto,and means for first warping inward together said legs and bands and thenclamping the same rigidly in such warped position.

3. A pole comprising hollow legs, transverse bands secured thereto,clamping means for warping inward together said legs and bands, and aninterior abutment arranged to co-act with said clamping means to rigidlyclamp said legs and bands in warped position.

41. A pole comprising hollow legs, transverse bands secured thereto,clamping means for warping inward said legs and bands, and a fillingblock arranged to co-act with said clamping means, said block having adrawn-in intermediate portion.

5. A pole comprising hollow legs, transverse bands secured thereto,clamping means for Warping inward said legs and hands, a filling blockarranged to co-act With said clamping means, said block having a drawninintermediate portion, and a recess adjacent said drawn-in portion toreceive said clamping means.

6. A pole comprising U shaped legs transverse bands, bolts to Warpinward together said legs and bands, and filling blocks to coact With"saidbolts, said legs having loolt receiving recesses therein to preventdisplacement of said'boltsi 7. A pole comprising U shaped legstransverse bands secured thereto and having portions thereof between thelegs dished or corrugated, and means for first Warping inward togethersaid legs and bands and then clamping the same rigidly in such Warpedposition.

In testimony whereof I edit; my signature in presence of tWo Witnesses.
